HJ l ATTDRNEYS Patented Mar. 10, 1953 UNITED STATES `-PAJIENT OFFICE SHIP ANCHOR Paul W. Polenz, LaJolla, Calif. Application September 29, 1950, Serial No. 187,557v s claims. (o1. 114-208) This invention relates to marine equipment, and more particularity to a ship anchor.

The object of the invention is to provide a ship anchor which will afford maximum holding power or resistance to dragging.

Another object of the invention is to provide a ship anchor which includes a novel locking mechanism which will not clog or become inoperative, due to entanglements with weeds, or other obstructions, the anchor being readily stored away when not being used.

Another object of the invention is to provide a ship anchor which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course oi the following description.

Figure i4 is a side elevational view, with parts broken away and in section, of another modied form of the anchor;

Figure 15 is a sectional view taken on the line iii-l5 of Figure 14.

Referring in detail to Figures l through 4 of the drawings, Athe numeral 3i) designates a base plate which may be made of any suitable material, such as metal, the base plate 35i including an intermediate at portion 3l that has projecting therefrom a pair of inclined flukes 32. The nukes 32 may be arranged opposite from each other, and the ends of the flukes 32 are provided with V- shaped notches 33, Figure 2. Also, thefree ends of each of the flules 32 Vare tapered, as at Sli, Figure l, such that when the anchor is being used, the iiukes will dig into the mud at the bottom of the river or sea, so that the anchor will not accidentally move.

Projecting from opposite ends of the center portion 3| of the base plate 3D is a pair cf tongues 35. The tongues 35 are preferably at, and these tongues help to prevent the anchor or base plate from acidentally turning over, as when the boat shifts its position. Projecting upwardly from the base plate 33 and secured thereto in any suitable manner is a vertically disposed upright or center piece 3S, Figure 1. The center piece 33 is pro-l vided with an arcuate slit 3i', and portions of' the slit 31 are arranged anguarly with respectto the main portion thereof, the angular portions of the slit 3l being designated by the numerals 38.

Pivotally connected to the center piece 35 is a shank or handle 3Q. The handle 3S has its lower end bifurcated so as to dene a pair of spaced, parallel legs ri, and extending between the legs 4!! and carried thereby is a pin 4|. The pin 4I is adapted to be moved through the slit 3l. As shown in Figure 3, the pin il can be positioned in one of the end angular portions 38 of the slit 31, so as to lock the shank. 39 in its adjusted position. A pin 42 extends between the lower ends of the legs 43, the pin A2 extending through slots 43 which are arranged in each of the legs 4D. The pin 42 also extends through the center piece 35, whereby a pivotal Vconnection is provided between the shank 39 and the center piece 36.

From the foregoing it is apparent that an anchor has been provided wherein accidental turning over of the base plate will be prevented due to the tongues 35. Also, the wide nukes 32 having tapered ends 34, will dig into the mud or bottom of the sea when the anchor is moved so as to offer a maximum drag or resistance to movement of the anchor. Also, the shank 39 can be locked in its adjusted position by means f o f the vpin 4l. Thus, by arranging the shank 39 so that the pin 4l is seated in one of the end portions 38, accidental pivotal movement of the shank 38 will be prevented. When it is desired to pivot the shank 39, tension on the shank 39 is released so that the pin 4I can move out of the portion 38, whereby the shank can be pivoted. A suitable rope or cable can be attached to the shank 39 by means of a ring 44, Figure 1, the ring 44 being attached to the upper end oi the shank 3Q.

In Figure 5, there is shown a modified base plate which is indicated by the numeral 45. The base plate 45 is adapted to be used in exactly the same manner as the base plate 30. The base plate 45 of Figure 5 includes a pair oi Qppositely extending tongues 45, and there are provided on each side of the base plate 4.5. a pair of flukes 4l. The base plate 45 further includes an upstande ing center piece 48. The tongues, nukes and center piece of the base plate 45 serve the saine functions as those parts which have been previously described in connection with Figures l through 4.

Referring to Figure 6, there is shown another modified base plate which is indicated generally by the numeral 49. The base plate 49 includes a plurality of spaced, parallel nukes G which are relatively narrow in width. Also, the base plate 49 is provided with a pair of oppositely extending tongues 5l and a vertically disposed center piece 52, these parts also serving the same functions as the nukes, tongues andcenter piece of Figures 1 through 4.

Referring to Figure 5f, there is shown a modivned anchor which'utiliz'es the base plate 30 and center piece 3B of Figures 1 through 4. In the assembly shown in Figure 7, the shank is indicated by the numeral 53 and has substantially the same construction and use as the shank 39. However, the shank 53 includes a pairof spaced, parallel, lower legs 54 which straddle the center piece 38. The legs 54 carry the usual or same pin 4l, the pin 4I projecting through the slit 31. The pin 42 which effects the pivotal connection between the legs 54 and the center piece 36 extends through open-ended slots 55 which are arranged in the bottom of the legs 54. Pins 29 project from center piece 36 Vfor engagement with legs 54 Referring tov Figures 8, Q and, 10, of the drawe ings, there is shown another modified ship aneher, wherein the bese pute. is. moieties gee.- erelly by the numeral 56.4 heee slate il; in,- cludes the nukes 51, and extending upwardly from the base plate is the center piece 5g. eri. ranged along the upper edge of the center piece- 5S and secured thereto in any suitable manner is a wedge 5S, there being one. of the wedges 5,!) arranged along each side of the center piece 58 The Wedge 5S is provided with arcuate. lower surface S2, Figure 8, and extending through the. center piece 58Y is a pair ot spaced, parallel, lock-- ing pins 60 and BI.

Pivotally connected to the center piece 5,8), isy a shank B3. The shank (53V is provided. with a pair of Seemed.y parallel .less 6.4. its lower endand the lese 64 Straddle the center piece 58.-. Each of the legs 54 carries a pin 6,5 which is adapted to engage with the lower surface o; the wedge A55. Projecting from opposite sides or each of the legs 64 is a pair or ears 56, Figure 8, and the ears E6 are adapted to engage one of the locking pins Si) or 6l so as to helpl prevent accidental pivotal movement or the shank 63 .v

The lower endV ofY each of the legs 64 is cut away to define a slot 6l, and a pin 68 projects through the registering slots 67 and through the center piece 58. The pin 68 thus provides a pivotal connection between the shank 63 and the center piece 58.

The anchor shown in Figures 8 through 10 thus can be arranged so that the shank 63 is in the position shown in Figure 8, or by releasing tension on the line to which the shank is attahed, the .shank can be arranged in the position shown in Figure 9. Or, if desired, the shank can be moved to a position so that the pin 60 engaged by one of the ears 66. The anchor will prevent accidental movement of the boat and can thus be locked in any desired position.

Referring to Figures 11, 12 and 13, there is shown another modied ship anchor, wherein the base plate is designated by the numeral 68. Extending from the base plate 68 are the flukes 65 and projecting upwardly from the base plate 68"- is a pair of vertically disposed, spaced, parallel center pieces lil, Figure 13. Exten-ding b etween the pair of center pieces 'lil and secured thereto in any suitable manner is a pair of spaced, parallel pins 'H and 1'2, and also extending between the pairs of enter pieces lil is a circular' rod T3.

Pivotally connected to the base plate is the shank 14. Secured to QDDosite sides of the shank 14 adjacent its lower end is a pair of legs l5, the legs l5 straddling the bar or rod I3 so that a pivotal connection is eiected between the shank 14 and the base plate. A 'lf-shaped cross piece 16, Figure 12, is secured to the lower ends of the legs l5. Carried by the shank 14' is a locking pin l1, Figure 13, and the looking pin H is adapted to engage the lower surface of the wedges 'H'. It will be seen from Figure 12 that the shank T4 can be arranged so that the locking pin 'll engages thev lower end portions of the wedges 7|', while at the sainel time one of the legs 'l5 abuts the pin 12. Thus, accidental pivotal movement ot the shank '1.4 will be prevented. When it is desired to move the shank 'I4 to a dierent position, tension on the cable or line to which the shank T4 is attached is released, whereby the shank 14 can be moved toward the pin 'I3 so that the pin 'll can slide beneath the Wedges li outil the shank i4 is moved to the desired location.

Referring to Figures 14 and 1,5 of the drawinte., there Shown another modified Shin e11- chor which includes a pair of spaced, parallel, vertically disposed @enter pieces 19., the base plate being indicated by the numeral 1.8,. Extending between the upper ends of the center pieces 'i9 are suitable spaced, parallel braces 8,0, the bracesA Si! serving t0 maintain the center pieces in their proper spaced relation. A shank 8l is pivotally connected between the pair of center pieces T9. For effecting they pivotal connection between the shank Si and the base plate i8, a roller 82 is mounted on a shaft 83, the shaft 83 being rotatably supported between center pieces T9. A crossbar` 34 is secured to the lower ends of the shank 8l, andthe shank 8| extends through registering slots in the roller 82 and shaft 83,. rlfhe crossbar 84 is adapted to be seated or received in registering cutouts 85 or 8.6 which are arranged in the lower surfaces of the center pieces l. When the crossbar 84 is seated in the cutouts 85 or 845, accidental pivotal movement 0f the. Shank 8l iS prevented- 'IO dieensese. the crossbar from the cutouts, the tension on the cable to which the shank is attached is released.

Suitable nukes 81 extend from the upper surfaces of the cross pieces 19, and when the anchor is being used, the flukes 81 will dig into the mud to thereby prevent shifting movement of the anchor.

From the foregoing it is apparent that an anchor has been provided wherein accidental cverturning of the anchor will be prevented, and also, the anchor is constructed so that a maximum amount of drag or resistance is provided. The shank can be pivoted or adjusted to various angles relative to the base plate. The locking means embodied in the anchor of the present invention will insure that the shank does not accidentally move from its adjusted position.

The locking mechanism of the ship anchor of the present invention can be readily disengaged. Since flukes extend from opposite ends of the base plate, the anchor is provided with twice the ordinary holding power. Also, there is suiiicient clearance between parts of the lock so that weeds or other objects will not accidentally become entangled therein and prevent operation of the anchor.
